Care Plan & Management
Description
1. The placenta implants in the lower uterine segment,
near the cervical os. The degree to which it covers the
os leads to three different classifications.
▪ Total placenta previa occurs when the placenta
completely covers the internal os.
▪ Partial placenta previa occurs when the placenta
partially covers the internal os.
▪ Low-lying or low-implantation placenta
previa occurs when the placental border reaches
the border of the internal os.
2. The incidence of placenta previa is three to six per
1,000 deliveries.
